Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to stirring implements, and more particularly pertains to a stirring implement of the disposable type utilized to stir beverages such as coffee and tea. Sugar, cream and non-dairy toners are frequently added to beverages such as coffee and tea. Currently, very simple stirring implements in the form a flattened straw are utilized to stir these beverages. While these conventional disposable stirring implements are inexpensive, due to their construction, they are inefficient at mixing settled sugar from the bottom of a beverage container with the beverage container liquid contents. Additionally, conventional teaspoons have a pointed tip construction which affords only a minimal contact with the bottom of the beverage container. In order to overcome these problems, the present invention provides a stirring implement which may be inexpensively formed so as to be disposable which has a flat blade construction to afford maximum stirring efficiency.

2. Description of the Prior Art

Various types of stirring implements are known in the prior art. A typical example of such a stirring implement is to be found in U.S. Pat. No. 1,477,653, which issued to C. De La Barre on Dec. 18, 1923. This patent discloses an elongated shaft having a rectangular blade pivotally attached at a distal end thereof. U.S. Pat. No. Des. 197,478, which issued to J. Larson on Feb. 11, 1964, discloses a food stirring implement having an elongated shaft provided with a rectangular stirring blade. U.S. Pat. No. Des. 235,307, which issued to R. Shoemaker on Jun. 10, 1975, discloses a combined spoon and spreading implement having a spoon and a scraping blade provided on opposite ends of an elongated shaft. U.S. Pat. No. Des. 256,212, which issued to E. Richmond on Aug. 5, 1980, discloses a combined spoon and chopper having culinary implements provided at opposite ends of an elongated shaft. U.S. Pat. No. Des. 268,077, which issued to A. Morin on Mar. 1, 1983, discloses a stirring implement having an elongated flat handle formed with an enlarged apertured stirring blade.

While the above mentioned devices are directed to stirring implements, none of these devices disclose a stirring implement which utilizes an elongated shaft having a thin flat blade with parallel side walls connected by radiused corners to a straight bottom edge to afford maximum stirring efficiency. Additional features of the present invention, not contemplated by the aforesaid prior art devices include the provision of a lateral projecting hook for engagement with the top side wall edge of a beverage container and a serrated utility cutting blade along with a transverse arcuately connected spreading blade to form a multi-utilitY stirring implement. Inasmuch as the art is relatively crowded with respect to these various types of stirring implements, it can be appreciated that there is a continuing need for and interest in improvements to such stirring implements, and in this respect, the present invention addresses this need and interest.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved stirring implement embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, it will be noted that the first embodiment 10 of the invention includes an elongated cylindrical shaft 12 having a thin flat stirring blade 16 attached at a distal end 14 thereof. A laterally extending hook member 13, for engagement with the top edge of the side wall of a beverage container such as a coffee cup, is formed intermediate the ends of the shaft 12. The blade 16 has parallel side wall portions 18 and 20 connected by radiused corners to a straight bottom edge 26. The parallel side walls 18 and 20 are connected by respective tapering upper

side wall portions

22 and 24 to the distal end 14 of the shaft 12.

FIG. 2 is a side view which further illustrates the construction of the hook member 13, which is disposed at a sufficient elevation with respect to the bottom edge 26 of the blade 16 so as to engage the top side wall portion of a standard sized coffee cup when the bottom edge 26 is resting on the interior floor portion of the cup. This allows the implement to be maintained in an unobtrusive location, but ready for immediate use, while the cup contents are consumed. It is contemplated that the stirring implement 10 may be inexpensively formed from a molded plastic material so as to afford disposability after use. The stirring implement 10 may be utilized along with the conventional form of disposable plastic foam cups.

FIG. 3 is a top plan view which further illustrates the orientation between the shaft 12, lateral hook 13 and thin flat stirring blade 16.

FIG. 4 is a bottom plan view, which further illustrates the relative orientation of these elements.

FIG. 5 illustrates a second embodiment 10' of the invention, in which like parts have been referenced utilizing the same reference numerals. The modified stirring blade 16' is provided with a transversely extending scraping blade 28 for use in spreading condiments such as margarine or jelly on pastry items. The opposite parallel side wall portion of the blade 16' is provided with a serrated cutting edge 32 for general utility food usage. A plurality of circular apertures 30 are spaced centrally along the blade 16' to facilitate a turbulent stirring action to further increase the stirring efficiency of the device. It is contemplated that the stirring implement 10' combines a stirring implement along with a multi-purpose culinary utensil into an inexpensive disposable device suitable for use at coffee break facilities where beverages such as coffee and tea are provided along with pastry items.

FIG. 6 is a side view which further illustrates the relative orientation between the scraping blade 28 and the stirring blade 16'.

FIG. 7 is a top plan view which illustrates the transverse arcuate connection of the scraping blade 28 with the stirring blade 16'. This construction also enables the scraping blade 28 to efficiently remove food materials from cylindrical side wall portions of a storage container.

FIG. 8 is a bottom plan view further illustrating the orientation of the previously described components.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents maY be resorted to, falling within the scope of the invention.
